<p>The natural ² / ³ / â¸U, ² / ³ / ² / Th and â´° / K radioactive content of vineyard soil was measured with an in-situ gamma-ray detector. The activity concentration measured with the in-situ detector are normalized using the laboratory-determined activity concentrations of several samples from the vineyard site. To determine the activity concentration of a particular soil sample, the gamma-ray photopeak detection efficiencies are required. In this work, the detection efficiencies were derived for each soil sample using gamma-ray photopeaks associated with the radionuclide of ² / ³ / â¸U, ² / ³ / ² / Th present in the sample, and the â´° / K, 1460.8 keV gamma-ray peak, from KCl salt.</p>
